Abstract

1327679 Velocity-modulated tubes SIEMENS AG 19 April 1971 [5 March 1970] 22875/71 Heading H1D An extended interaction klystron provides a high quality linear gain characteristic, despite operation with an electron beam of greater than 3 micropervs, by reason of the fact that, for an extended interaction resonator, the electronic loading may be made very small by suitable choice of beam speed, high frequency decoupling between the resonators being achieved by spacing successive resonators a quarter plasma wavelength apart. A 5 resonator klystron employing an annular beam, resonators formed by sections of helix, and electromagnets for focusing, is described.
